Description

La présente invention est un accessoire adaptable à des lunettes correctrices ou de protection pour améliorer la vision des détails, selon le grossissement utilisé.The present invention is an accessory adaptable to corrective or protective glasses to improve the vision of details, depending on the magnification used.

Dans les dispositils connus de ce genre, il est très souvent utilisé un serre-tête muni de loupes, de loupe montée sur pied ou plus simplement de loupe tenue à la main. A mon avis, ces dispositifs sont d'une utilisation inconfortable et malaisée, du fait de leur encombrement.In known devices of this kind, it is very often used a headband provided with magnifying glasses, magnifying glass mounted on a stand or more simply a magnifying glass held in the hand. In my opinion, these devices are uncomfortable and awkward to use, due to their size.

Le principe utilisé, dénommé MAXI-VISION, permet une utilisation particulièrement simple et rationnelle de verres grossissants pour tout travai exigeant une excellente vue des détails et par conséquent améliorent la qualité de la finition. Cet accessoire est fixé sur la monture d'une pair de lunettes classiques par un système auto-écarteur activé par une tige d'acier coudée en demi-cercle et des petites pattes coudées qui se posent de chaque coté des verres, niveau nasal. Ce système se pose et se dépose instantanément par une simple pression.The principle used, called MAXI-VISION, allows a particularly simple and rational use of magnifying glasses for any work requiring an excellent view of the details and consequently improve the quality of the finish. This accessory is fixed on the frame of a pair of classic glasses by a self-retracting system activated by a steel rod bent in a semicircle and small bent legs which are posed on each side of the glasses, nasal level. This system is installed and removed instantly with a single press.

Le centrage des verres grossissants situé à environ 70 mm de la surface des verres se réalise très aisèment par une vis moletée montée sur axe à double pas de vis inversé.The centering of the magnifying glasses located approximately 70 mm from the surface of the glasses is very easily achieved by a knurled screw mounted on an axis with a double inverted screw pitch.

Tel qu'il est représenté, ce dispositif comporte une paire de verres grossissants qui se glissent chacun dans une cage de profil adéquate.As shown, this device comprises a pair of magnifying glasses which each slide into a cage with an adequate profile.

Bien entendu il est possible, selon le degré de grossissement désiré, de modifier à volonté la puissance des verres adjoints.Of course it is possible, depending on the desired degree of magnification, to modify the power of the adjoining glasses at will.

Ce dispositif permet en outre de regarder en déplaçant son regard du dessus des verres grossissants sans faire un seul geste et en conservant les mains totalement libres.This device also allows you to look by moving your gaze from above the magnifying glasses without making a single gesture and keeping your hands completely free.

Le poids de cet accessoire n'aggrave en rien le confortcar son poids est négligeable.The weight of this accessory does not worsen the comfort because its weight is negligible.

Ce dispositif, objet de l'invention, peut être utilisé dans tous les cas ou l'utilisateur vent améliorer la perfection des débits de son art ou de son geste ; il peut donc être utilisé avec le plus grand succès et pour l@ satisfaction de tous, dans le domaine médical, industriel, artistique et dans toute activité où l'on veut voir encore mieux et s'approcher de la perfection. This device, object of the invention, can be used in all cases where the user wants to improve the perfection of the flow of his art or his gesture; it can therefore be used with the greatest success and for the satisfaction of all, in the medical, industrial, artistic field and in any activity where one wants to see even better and approach perfection.
